JavaScript calculates the current day of the week

Get current week / * get current day of the week * * / function getWeekDate () {var weeks = new Array ("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"); var now = new Date (); var day = now.getDay (); var week = weeks [day]; return week } alert (getWeekDate ())

Description:

The getDay () method returns a number that represents the day of the week.

DateObject.getDay ()

DateObject refers to the day of the week, using local time. The return value is an integer between 0 (Sunday) and 6 (Saturday).

So if you need to give the exact day of the week, you need to define an array of Array ("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday").

Then take the number returned by getDay () as the subscript and fetch the corresponding week value from the array.
